Crown

The crown is the small knob on the side of your watch — but it plays a big role. It’s your direct control point for setting the time, winding the mainspring, and sometimes adjusting the date or other functions.

What the Crown Does:

  • Manual Winding: Winds the mainspring in manual and automatic watches
  • Time Setting: Pull and rotate to adjust the hour and minute hands
  • Date/Function Control: On watches with calendar or other features
  • Water Resistance Seal: In many models, especially diver watches, the crown helps seal the case

Waterproof screw down

A screw-down crown is a specialized crown mechanism designed to create a watertight seal, commonly found in diver and sports watches. Unlike a regular push-pull crown, it screws securely into the watch case to prevent water, dust, and moisture from entering the movement.
Why It Matters:
  • Enhanced Water Resistance: Helps watches stay sealed at depths up to 100m or more
  • Protects the Movement: Prevents internal damage caused by moisture or debris
  • Essential for Divers & Swimmers: Ensures safety during water exposure
At Watch Service 360, we specialize in servicing and restoring waterproof features, giving you peace of mind in or out of the water.
Stay protected. Stay precise. Trust your crown to the experts.

Japanese waterproof

Japanese watch brands like Seiko, Citizen, and Casio are renowned for designing waterproof crowns that provide reliable protection for daily wear and professional use. These crowns often feature screw-down or push-in designs with reinforced gaskets to prevent water, dust, and moisture from entering the watch case.

Whether it’s a Seiko diver, a Casio G-Shock, or a Citizen Eco-Drive, we ensure your crown functions flawlessly, keeping your watch protected from the elements.

Japanese reliability. Watertight performance. Expert care at Watch Service 360.

Waterproof O-Ring

The O-ring is a small but essential rubber gasket used in waterproof watches. Found in the crown, case back, and crystal area, the O-ring forms a tight seal that keeps water, dust, and moisture out of your watch’s movement, protecting its delicate internal components.

At Watch Service 360, we treat your O-rings like a first line of defense, ensuring your timepiece stays sealed and protected in all conditions.

Small part. Major protection. Keep your watch waterproof with expert O-ring care.

Antique

The crown of an antique or vintage watch isn’t just functional — it’s a part of the watch’s identity and design. These crowns were often uniquely shaped, branded, or crafted to match the era and style of the timepiece.

Over the decades, antique crowns can become worn, loose, rusted, or lost, compromising both the watch’s functionality and its historical value.

Whether you’re restoring a pre-war pocket watch or a mid-century wristwatch, Watch Service 360 is committed to preserving the originality and function of your vintage timepiece.

Timeless charm. Period-correct parts. Expert restoration.

Dustproof

A dustproof crown is designed to protect your watch movement from one of its worst enemies: microscopic dust and debris. These crowns are typically fitted with internal gaskets or sleeves that form a tight seal around the winding stem and case opening, especially in vintage and field watches.

While not fully waterproof, a dustproof crown prevents particles from entering the watch, which can lead to wear, clogging, and timing issues.

At Watch Service 360, we preserve your timepiece’s integrity, ensuring your dustproof crown performs exactly as intended, especially in older or rare watches.

Invisible protection. Long-term precision. Expert crown care.

Dress

Dress crowns are designed with sophistication in mind, complementing the refined aesthetics of formal and minimalist watches. Typically smaller, flatter, and often recessed into the case, they maintain a sleek profile while still offering essential functionality.

Unlike large, rugged crowns found in sports or diver watches, dress crowns prioritize visual harmony and comfort, especially when worn with shirts or suits.

Whether you’re restoring a vintage dress watch or maintaining a modern one, Watch Service 360 ensures your crown functions smoothly and looks flawless.

Elegant design. Seamless function. The finishing touch your watch deserves.
